APPARATUS FOR BURNING HYDROCARBON OILS.

SPECIFICATION forming part of Letters Patent No. 428,353, dated` May 20,1890.

Application led July 13, 1889. Serial No. 317,449. (No model.)

To @ZZ whom it may concern:

Beit known that I, ETHAN ROGERS, of Ballston, in the county of Saratogaand State of New York, have invented a new and Improved Apparatus forBurning Hydrocarbon Oils, of which the following is a full, clear, andexact description.

Two systems are employed in the burning of crude oil in forges when airis used as au atomizer, one system being to compress the air and use itunder comparatively heavy pressure and the other system being to employa fan-blast of comparatively light pressure. In the lirst system the oilis forced through the burner by the compressed air, and cannot possiblyget to the fire Without a supply of air to vaporize it, and consequentlya supply of air to carry on sufiicient-combustion to consume thevaporized oil; but this method of burning oil is expensive, in that acostly plant is required to compress the air, and, on the other hand,when a fan-blast has been employed there is great danger of explosionand fire, as the oil is taken to the burner either by gravity or bypumping, the pump acting independently of the fan, so that if the blastis shut off for any reason the pump may continue to act, and Oil willthus be delivered to the burner without the required quantity of air tocarry on combustion.

The object of my invention is to overcome the di'iculties heretoforeexperienced in burning oil by means of a blast; and to the ends namedthe invention consists, essentially, of a system or arrangement by meansof which the pump employed to raise the oil so that it will i'low to theburners is driven by the belt employed to drive the fan, andconsequently the fan must operate at all times when the pump isoperated. In this way I insure the delivery of the required amount ofair to the burner at all times when the pump is in operation.

Reference is to be had to the accompanying drawing, which is adiagrammatical view of my improved system of burning oil.

In the drawing, 10 represents an oil-tank of a capacity such that itwill hold one days supply of oil. -Vithin this tank I mount acentrifugal pump 11,whieh delivers to a standpipe 12, that leads to areturn-pipe 13, of larger diameter than the stand-pipe,the return-pipe13 extending upward Athrough the roof of the building and to the openatmosphere. From the stand-pipe 12, I lead the main deliverypipe 14,from which there are branch pipes 15, that lead to the forges 16, thepipe 14 being upon an incline, such that when the pump ceases to act alloil contained within the pipe 14 and within the pipes 15 will flow backto the stand-pipe, and thus into the tank again.

To provide a proper air-blast, I arrange a fan 2O in any convenientposition, and this fan I drive by means of a belt 21, which runs upon apulley carried by a counter-shaft 22, said counter-shaft in turn beingdriven by a belt- 23, which runs upon a pulley carried by a line-shaft24, and in order that the pump 11 may be driven only when the fan 2O isdriven I provide its shaft 25 With a pulley 26, that is engaged by abelt 27, which runs upon a pulley carried by a counter-shaft 28, saidcounter-shaft carrying a pulley, which in turn runs in engagement Withthe belt 2l, the countershaft being so mounted in practice that it willact as a belt-tightener for the belt 21.

In connection with the main blast or wind pipe 30 of the fan 20,Iarrange pipes 31, which lead to the burners 32 of the forges 16, and inpractice I prefer that the burners 32 should be similar to the burnerillustrated,described, and claimed in my application for Letters Patentof the United States iled concurrently herewith. At all events, I would.provide a burner wherein the blast slide or valve should be so arrangedthat it would be impossible to cut off the full supply of air.

From the construction above described it will be seen tlllat the pump l1cannot be called into play vunless the fan 20 is at the same time drivento deliver a blast to the burners 32, and consequently all danger offlooding the burners and the forges is avoided.

Now, although I have illustrated a specic construction whereby the fanand pump are simultaneously driven, I desire it to be understood thatthis construction might be varied Without departing from the spirit ofmy invention, the underlying principle of the invention being thedriving of the pump through the medium of the fan-driving mechanism.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- IOC.

1. An apparatus for burning hydrocarbon' oil, consisting of a burner, anoil-tank below the burner, a stand-pipe leading up through the tank, aninclined pipe 14, connected at its lower end with the stand-pipe betweenthe ends thereof and connected at its higher portion with the burner, apump for raising the oil into the stand-pipe above the burner, anair-pipe also connected with the burner, a blower connected therewith, abelt operating said blower, and a second belt operating the oil-pumpshaft from the first-named belt, substantially as set forth, wherebywhen the fanbelt ceases from any cause to operate the oilpump willsimultaneously stop and the oil return by gravity to the tank from theburner, substantially as set forth.

v2. In an apparatus for burning hydrocarbon oil, the combination, withthe oil-tank 10, a stand-pipe 12, extending up therethrough, areturn-pipe 13, connected between its open ends with the upper end ofthe stand-pipe and at its lower end entering the tank, a centrifugalpump on the lower end of the standpipe for raising the oil therein, anda vertical shaft leading down through the tank to the said pump, oftheburner, a pipe leading from between the ends of the stand-pipethereto, a blower having a pipe connecting it with the burner, aline-shaft, a belt driving the blower therefrom, and a second beltdriven by said first belt and operating the vertical shaft of the pump,substantially as set forth.

3. An apparatus for burning hydrocarbon oil, consisting of a burner, anoil-tank below the burner, a stand-pipe leading up through the tank, aninclined pipe connected at its upper end with the burner and at itslower end with the stand-pipe between the ends thereof, an air-blastpipe connected with the burner, a centrifugal purnp at the lower end ofthe stand-pipe for forcing the oil upwardly therein, and an overowleading from the upper part of the stand-pipe into the tank,substantially as set forth.
